"I am 63. I am scared for my own life. You should be too. And I am absolutely terrified for the life of my son."

Says one of the experts at the UK National Emergency Briefing. The video is a medley of just a few of the best Oh-Shit-Moments.

Tim Lenton appears as well. His short Oh-Shit scene relates to the AMOC slowdown.
And by the way: the Utrechter Team around #vanWesten published a new study.

"Abrupt Gulf Stream path changes are a precursor to a collapse"
High-resolution modelling reveals an exact Oh-Shit location for observing imminent tipping: 2 years before tipping into the collapse phase, the Gulf-Stream surface water transport ( one part of the AMOC), jumps 200km north.
Instead of turning right near Cape Hatteras, it then continues North and only turns right on the latitude of Philadelphia.
The area between the two turning points also experiences an equally sudden jump in surface temperature of +6°C.

These surface changes occur because the deep-water current beneath it stops its Southward flow.

RE: @sflorg@mastodon.social

Unmanaged rewilding >of a previously human-controlled environment< indeed decreases biodiversity even further.
The animals required for ensuring a good mix of open woodland, meadows, and forest don't exist anymore. And so, a natural rewilding of such post-human land leads to shrub-dominated flora.
It takes quite a while for this to change into a balanced and diverse flora and fauna.
Longer still for rewilding of a post-civilisation, climate-change_impacted region.

Good writeup of a paywalled paper:

I asked an author for an uploaded PDF so might post a link to that later. https://onlinelibrary.wiley.com/doi/10.1111/ele.70325

The Black Death pandemic from 1347ff is not a blueprint however for what's in store for European post-civilisation landscapes.
The pre-pandemic population of the whole continent was only 60 mio people, that is today's UK population.
So their #landuse was much, much smaller. Forests still were home to wolf packs and bears, one of the prerequisites for a healthy #biodiversity.

Another thing I'd like to get an answer for: how much does the water cycle change with rewilding, ie with shrub-ification?
Will a post-civilisation East-Germany and Poland still turn into dry steppe as projected for >1.5°C?
Or will the shrub-ification counter this climate change impact by increasing cloud-nuclei and rain amounts?
